There is an issue when downloading a large file (which take some minutes to complete).

The endpoint returns 200, but after around 90 seconds waiting the download the connection is prematurely closed.

I tried to set a higher timeout for this connection.
Tried to upgrade Spring Boot and Java.
Nothing worked.
